Description:
------------
The documentation indicates that the offset describes the number of characters from the front of the string, and that the search will -start- at the offset and move toward the beginning. 

However, the offset seems to be ignored.

Test script:
---------------
$buffer = '01234567890123456789';
var_dump(strrpos($buffer, '0', 5));


Expected result:
----------------
int(0)

Actual result:
--------------
int(10)

The offset controls the start or end point for the search: positive offset is the ending point, negative offset is the starting point (from the end). So $offset=5 means to search from the end towards the beginning as usual but to stop at offset 5, and $offset=-5 means to search from offset ending-5 to the beginning.

According to that, the documentation should be changed to read like
 >offset
-> If specified, search will start this number of characters counted from the
+> If specified, search will end this number of characters counted from the
 > beginning of the string. If the value is negative, search will instead start
 > from that many characters from the end of the string, searching backwards.

Well, the respective documentation has been improved a while ago,
so I think this ticket can be closed.
